L-bursts

This dynamic spectrum recorded at the University of Florida
Radio Observatory shows the typical time vs. frequency behavior
for a series of Jovian L-bursts. Unlike S-bursts,
the instantaneous bandwidth of an L-burst is very large, often
greater than 5 MHz. L-bursts have a slow undulating quality that
reminds many listeners of waves crashing on a distant beach.
Note that in this dynamic spectrum the horizontal (time) axis
is over 90 seconds long. In the S-burst
dynamic spectrum the time axis covers just 160 milliseconds.
